Security privacy protection method and system based on ECC encryption

Abstract

The invention discloses a security privacy protection method and system based on ECC encryption. The method comprises the following steps: user equipment applies for registration from local terminal equipment; the local terminal equipment judges the mutual relevance of keys and the consistency of MAC addresses, generates a random authorization key if judging the keys as being legal, encrypts the random authorization key through a public key and sends the encrypted authorization key and a registration success message to the user equipment; the user equipment decrypts and stores the encrypted authorization key through a unified public key and applies a communication key from the local terminal equipment; the local terminal equipment generates a random communication key, encrypted the communication key through the generated authorization key and sends the encrypted communication key and an application reply of the communication key to the user equipment; and the user equipment decrypts the received encrypted communication key, and then the user equipment and the local terminal equipment encrypt and decrypt interactive data communication through the communication key.

Description

technical field [0001] The present invention relates to a security and privacy encryption technology based on ECC (Elliptic Curves Cryptography, elliptic curve cryptography), in particular to a security and privacy protection method and system based on ECC encryption. Background technique [0002] EOC is the abbreviation of Ethernet Over Cable (Ethernet Over Cable), that is, based on coaxial cables, various digital modulation technologies are used to carry Ethernet and other comprehensive services. Due to the urgent need for triple play in the national strategy, and EOC is one of the key technologies for triple play, more and more chip and equipment manufacturers have invested in the research and development of EOC systems. However, although various EOC systems have their own advantages in speed, anti-noise and anti-interference, they are still not perfect in terms of communication security. [0003] For the access authentication of different networks of the same device, th...

Problems solved by technology

However, because the encryption scheme uses a fixed key pair, whether it is user encrypted registration or subsequent secure communication, it is easy to be cracked by eavesdroppers, resulting in unsafe events such as user privacy data leakage and illegal device access to network services.
